Answer:
x=2±16i
Step-by-step explanation:
1.) Using the PEMDAS distribute the using the FOIL method
2.) Distribute the -16 to ()
3.) Add the -25 to the equation
=0
4.) Since this isn't factor-able, you must use the quadratic formula,
and distrubute the numbers
a=-16 b=64 and c=-89
5.) Simplify the radical by finding the factors of -18688 that has a perfect root as one of the factors (which is -256 and 73).
6.)Simplify the fraction
7.) Your two roots are:
{2}(+ or -)16i\sqrt{73}
